i did not have experience with these issues. I am not sure what license agreement says, can you monetize your videos with AJ sounds and music under it..You can ask envato support, or you can make a forum thread to see what others say

usual license agreement would be that i just send a confirmation email in which i give you just written permission to use my item after purchase in youtube.but that is not legal document, just a written email.please contact me via email
